In that case (as with the Supreme Court example that Steve cited earlier), I'm sure the alliteration wasn't intentional, for any particular effect. It's more likely that there were no other word choices available to express those particular concepts.

Regardless, it's fun to spot serendipitous alliteration. Being able to pick up on it will eventually make alliteration part of your natural mindset, and you'll be more likely to be able to use it well in your writings.
